Phil and friends has several Official SBD recordings for free on Archive 4/20/01 is one I can think of off the top of my head
Ratdog has SBD's available pre- 2003
Just gotta poke around.....
policy is not to post them till after 4 months have passed i believe seems fair they deserve to recoup some money from the soundboards,the fact they still allow free trading is awesome
If i told ya all that went down,it would burn off both your ears
You can also find sbds on sugarmegs.org They only have Furthur sbds from around Sept 09, then mostly aud tapes, but they do have an excellent collection of GD sbds including many very tasty Betty Boards.
